Hello, i'm developing vb.net application, i have a problem even if the command connect give me result ok, when i send data i got always you must send data only if websocket is open...
Could you help me:?

Private websocket As WebSocket4Net.WebSocket
Sub Main()

WebSocket = New WebSocket4Net.WebSocket("wss://ws.binaryws.com/websockets/v3")
AddHandler WebSocket.Opened, Sub(s, e) socketOpened(s, e)
AddHandler WebSocket.Error, Sub(s, e) socketError(s, e)
AddHandler WebSocket.Closed, Sub(s, e) socketClosed(s, e)
AddHandler WebSocket.MessageReceived, Sub(s, e) socketMessage(s, e)
AddHandler WebSocket.DataReceived, Sub(s, e) socketDataReceived(s, e)

websocket.Open()
Console.WriteLine(websocket.State)

websocket.Send("{""ticks_history"":""R_50"",""end"":""latest"",""count"":10}")

End Sub

Sub socketClosed(s As Object, e As EventArgs)

End Sub

Sub socketError(s As Object, e As SuperSocket.ClientEngine.ErrorEventArgs)
MsgBox(e.Exception.ToString
)
End Sub

Sub socketMessage(s As Object, e As WebSocket4Net.MessageReceivedEventArgs)
MsgBox(e.Message)
End Sub

Sub socketDataReceived(ss As Object, e As WebSocket4Net.DataReceivedEventArgs)
MsgBox(e.Data)
End Sub

As per the screenshot, you are sending ping just after websocket.open that will not work as websocket is not opened yet. need to move that ping in socketMessage

I get it. When you call Websocket.Open it asks the websocket to open, but doesn't wait for the socket to open. That is why the ping request fails.
